1) the plane can sustain a climb at about 55 to 60 degrees, around 90mph. Umm, wrong.

2) there's no stall to speak of, pulling up to 60 degrees clean will cause a mush-out, but that's about it, you can pull right back up.

3) you can shoot down B-17s with the 7.9's alone. I'm not sure if this is a B-17 problem or a He problem though.

Looks to me like the 3D model is fine (no, superb in fact) but it seems like the FM is the 109 with a much bigger engine grafted on.

So, where to start to fix this? Seems like a good project for me. And anyone got a few labled cockpit photos for it?

I read that luftwaffe pilots disliked it because of the high wing loading.. the turn rate/stability could use some looking at. They didn't see any action.

Here's what I have on it:

He-100

Origin: Ernst Heinkel AG
Type: Single-Seat Fighter
Engine: 1,175hp Daimler-Benz DB601 Aa inverted V12 liquid cooled
Dimensions: Span 30ft 10 3/4 in; length 26ft 10 3/4in; height 11ft 9 3/4 in
Weights: (D-1) empty 3,990lb; Max loaded 5,512lb
Performance: (D-1) maximum speed 416mph; service ceiling 36,090ft; range 559 miles

Undaunted by loss of the Luftwaffe's fighter orders to BFW with the 109, Heinkel proposed a much faster fighter, with structure completely different form the rather unimpressive He 112 to make it more efficient and much quicker and cheaper to build. The resulting Projekt 1035 was completed on 25 May 1937 and at the end of that Year the now-informed RLM sanctioned a prototype and ten pre-production machines. Heinkel managed to secure number "100" though this had been previously alotted to Feiseler. The first prototype flew on 22 January 1938, and was clearly oustandingly fast, being small and having a surface-evaporation cooling system instead of a draggy radiator. Though there were many problems, and Luftwaffe test pilots disliked the high wing loading, Udet himself flew the V2 to a new world 100km circuit record at 394.6 mph. On 30 March 1939 Hans Dieterle, flying the clipped-wing V3 took the world speed record at 463.92 mph. But the RLM saw no reason for mass production, and six prototypes were sold to the Soviet Union and three He 100D-0 to Japan, with armament of two MG 17 and a 20mm MG/FF. The remaining 12 He100D-1 fighters formed a Heinkel-Rostock defence unit, but in 1940 were publicised by Goebbels' propoganda machine in such a way as to convince Britain there was a fighter in large-scale service called the "He 113".

Although Messerschmitt's Bf109 had been adopted as the Luftwaffe's standard monoplane fighter in preference to Heinkel's He112 submission, Heinrich Hertel and Siegfried Gunter designed a new high-speed fighter with a design maximum speed of 435mph. It was also engineered for ease of production with few curves and the minimum number of parts and components. The resulting Heinkel He100a prototype made its first flight on 22 January 1938, powered by a Daimler-Benz DB601 engine with a special pressurised evaporative cooling system. A second prototype, with a DB601M engine, captured the 100km closed circuit landplane record on 6 June 1938, piloted by Ernst Udet. The aircraft was referred to officially as an He112U, to boost the reputation of the He112B sold to Japan and Spain. The third prototype, built for an attempt on the world absolute speed record, had reduced wing span, a more streamlined cockpit canopy and a boosted DB601 engine but it crashed in September and was replaced by the similar eight prototype. In this aircraft Hans Dieterle raise the record to 463.92 mph at Oranienburg on 30 march 1939. The fourth and fifth aircraft were designated He100B, prootypes six, seven, and nine were completed to He100C standard; the third of these was the first He 100 to be armed carrying two 20-mm MG FF cannon and four 7.92 mm (0.31in) MG17 machine guns.

Handling deficiencies revealed during service evaluation at Erprobunstelle Rechlin resulted in introduction of the He100D with enlarged tail surfaces and with a conventional, semi-retractable ventral radiator in place of the earlier enclosed system. It was armed with a 20-mm MG FF cannon in the nose and two 7.92-mm MG17 machine guns in the wings. Fifteen He100Ds were built, comprising three He100D-0 pre-production examples and 12 He100D-1 production aircraft, the latter being retained at Heinkels Rostock-Marienehe factory and flown by Heinkel staff pilots as a local Defence unit. As DB601 engines had been earmarked for Bf109 production, the He100 was not adopted for Luftwaffe use and the company was authorized to offer it for foreign license-manufacture. In October 1939 Japaneese and Soviet teams visited Marienehe and, as a result, three He 100D-0 aircraft were sold to Japan and six of the prototypes to the USSR. Proposed Japaneese production did not materialize.

the Ki-61 was based on the He100 which japan got from german. If the pilot size is right on the Ki-61 then the plane is way to small. I think this may be a problem on the He100 also.

The He100 was the first "real" new plane the community was given. Vanderstock shocked and amazed us all with a beautiful plane and cockpit out of the blue. Then things really started taking off with openplane. Any of you "old timers" remember that?

True, true.

Ahh, good point! One of the things I forgot to mention was that I was able to hold a 5gee turn at about 300mph with an almost level attitude. Again, this leads me to belive that the power loading is way off (ie, tweaked engine to overcome drag and get a 109 doing 415mpg).

BTW seems to me that the 100 is the _real_ "what if" plane of the war. The jets were cool, but the 100 could have been in action during BoB, and it seems to me it would have completely outperformed the Spits and had better range than the 109. Those two items alone seem to suggest that this plane could have changed things.

Then consider the plane in action against the 8th, 100's with 605's instead of 109G's. Methinks this thing could have run and played with the 51's, which would have made that a different game than them fighting the outperformed 109's and gasping-for-breath 190's.

True, but about three to four months too late. By the time they were ready for widespread introduction, the 51's had swept the skies clear of the LF. They should have done and all-out to get _something_ into service for early '44, but they didn't and took a leisurely approach to the Dora. The issue is that the 100 could have easily been in widespread use, and while not perfect for this mission (small wings like the 190) it would have certainly been better at it than the 109's. Consider that it would have had a 605 at that point too.

The HE wasn't so much a bad plane, but just not good enough.. perhaps if more engineering went into them, they could have been more like the german 51B & D.

Well I think it just needed the few years that the 109 got. It was generally 60mph faster than the 109 on the same engine, so my guess says that it would have been largely equal to the 51 in performance.
